Connect to cluster via Slurm REST API

Start and cancel a workflow in the cluster via the Slurm REST API.

Python bindings from an OpenAPI specification can be created with OpenAPI Generator. Use the option library=asyncio to create an async client.

The request to submit a Job looks like this.

POST http://<cluster ip>/slurm/v0.0.38/job/submit
{
    "script": "#!/bin/bash\n nextflow run <workflow url> -c /mnt/config-bucket/<workflow config> -hub <github|gitlab|bitbucket> -revision <git commit SHA>",
    "job": {
        "current_working_directory": "/vol/spool/clowm-workflows",
        "name": "<execution id>",
        "requeue": false,
        "environment": {
            "NXF_HOME": "/home/slurm/.nextflow"
        }
    }
}
